This year the Ramadan starts on the 9th of July. The month of Ramadan is a month of partial fasting and extra prayers. Muslims fast from dawn till dusk, and that includes not drinking. As the Islamic calendar is a lunar calendar, the months migrate through the seasons, moving forward every year by 11 to 12 days. A Lunar calendar is based on the cycle of the lunar phase. Twelve lunar months make up 354,37 days.
Ramadan dates can vary in different countries depending on whether one goes with the calculated time of the new moon, or the actual sighting of the new moon. All countries on the planet will see the new moon within a 24 hour period, starting from the first sighting in the east
The lunar calendar with twelve months, the Hijri Qamari, is the official calendar in Saudi Arabia. Other lunar calendars may include the addition of extra months to synchronise them to the solar calendar and make them better linked to the seasons, and are in fact ”lunarsolar” calendars. Most calendars used in antiquity had some adjustment to bring it in synchronisation with the solar year.
In the hijri lunar calendar it takes about 33 years and five days for the month of Ramadan to migrate through the solar year and end up where it started.
Muslims believe that Ramadan is the month when the Quran was revealed. We know it moves up 11 to 12 days every year, and that it takes 33 years and five days to make the cycle through the solar year, so we could calculate when exactly the Quran was revealed on the Gregorian calendar.
